Definitions

  • the present invention relates to a device for controlling an automobile vehicle gearbox in which the movable elements, whether they concern sliding gears, synchronizer sliding elements or sleeves, are shifted by means of parallel slidable yokes on which act a main control finger member which pivots for alternately sliding each of the yokes in at least one direction and change the gear ratio.
  • the main finger member is connected to rotate and move in translation with a control shaft which is slidable in a direction perpendicular to the common sliding direction of the yokes so as to permit the engagement of the main control finger member in one of the yokes for selecting at least one gear ratio.
  • the gear lever having two perpendicular directions of pivotal movement is shifted along four parallel paths.
  • the two central paths permit, after selection, engaging the first four forward gear ratios while the two lateral end paths respectively permit engaging the fifth forward gear ratio and the reverse gear.
  • this design requires a relatively complicated mechanism involving large movements of the control linkage connecting the gear lever to the gearbox. The result of this complexity is a relatively large overall size and lower reliability of the gearbox control device.
  • An object of the present invention is to propose a control for a gearbox which overcomes the drawbacks just mentioned and permits effecting the selection of the forward gear ratio of the highest rank and of the reverse gear in the same lateral position of the gear lever, i.e. along a single selection path.
  • the invention therefore provides a control device of the aforementioned type which comprises an auxiliary control finger member which is pivotable about the axis of the control shaft for causing the sliding of one of the two lateral end yokes in a first direction and engaging the reverse gear ratio, it only being possible to shift the other lateral end yoke by means of the main control finger member in the opposite direction for changing to the forward gear ratio of the highest rank, a first transverse abutment preventing the sliding of the reverse yoke in said opposite direction, a second transverse abutment preventing the sliding of said other yoke in said first direction, said other yoke being provided with a ramp with which cooperates the main control finger member when it is shifted in said first direction for causing its lateral disengagement from said other yoke and permitting the pivoting of the auxiliary control finger member by driving means interconnecting the two control finger members.
  • the driver merely has to shift the gear lever in only three parallel paths, the reverse gear or the fifth gear being engaged by shifting the gear lever in one of said paths respectively in one or the other direction.
  • the ramp is so oriented as to cause the lateral disengagement of the main finger member from the side opposed to the other yokes.
  • the auxiliary control finger member is also connected to rotate and move in translation with the control shaft; the lateral distance between the two control finger members which are thus interconnected exceeding the lateral distance between the two lateral end yokes.
  • the control device comprises a control stirrup mounted on the control shaft relative to which it is freely pivotable and immobilized in translation relative to the case of the gearbox, said stirrup having one lateral branch constituting the auxiliary control finger member permanently engaged in the reverse gear yoke, whereas the other branch includes at its end a driving yoke which is in juxtaposed relation to said other yoke for engaging the forward gear ratio of the highest rank, in which comes to be engaged the main control finger member after having been laterally disengaged from said other yoke when engaging the reverse gear.
  • FIG. 1 is a simplified partial sectional view of a gearbox having five gear ratios or speeds arranged in accordance with the teaching of the present invention
  • FIG. 2 is a diagram showing the movements of the gear lever for selecting and engaging the various gear ratios of the gearbox
  • FIG. 3a is a diagrammatic perspective view of the control device shown in FIG. 1, the gear lever being in the neutral position between the third and fourth gear ratios;
  • FIG. 3b is a sectional view taken on line 3--3 of FIG. 1, the control device being in the position illustrated in FIG. 3a;
  • FIGS. 4a and 4b are views similar to those of FIGS. 3a and 3b, the gear lever being in the position for selecting the fifth gear ratio or the reverse gear;
  • FIGS. 5a and 5b are views similar to those of FIGS. 3a and 3b, the fifth gear ratio being engaged;
  • FIGS. 6a and 6b are views similar to those of FIGS. 3a and 3b, the reverse gear being engaged, and
  • FIGS. 7a and 7b are views similar to those of FIGS. 3a and 3b of a second embodiment of the control device of the invention.
  • FIG. 1 shows an internal control device of a gearbox, a part of the case 10 of which can be seen.
  • the control device comprises a control shaft 12 which permits the selection and the engagement of the various gear ratios.
  • the shaft 12 is rotatively and slidably mounted in two bearings 14 and 16 of the case 10.
  • a control sleeve 18 is mounted on the control shaft 12 to which it is connected in translation and rotation.
  • a main control finger member 20 is mounted on the sleeve 18 and a pin 22 connects the main control finger member 20 and the control sleeve 18 to move in translation and rotation with the control shaft 12.
  • the control shaft 12 is shifted laterally by means of a selection lever having an end portion 24 which drives a washer 26 mounted on the sleeve 18.
  • the lateral movements, i.e. the movements parallel to its main axis, of the control shaft 12 permit the selection of the gear ratios, as will be explained hereinafter.
  • the control shaft 12 is rotated by means of a gear shift lever 28 fixed by means of a pin 30 to a free end portion of the control shaft 12. Under the action of the shift lever 28, the control shaft 12 can pivot about its axis in either direction for engaging a gear ratio of the gearbox.
  • the control shaft occupies a position illustrated in FIGS. 1, 3a and 3b, in which it is maintained by an automatic re-centering device formed by two slidable rings 31 and 32 between which is interposed a spring 34 which biases these rings away from each other.
  • the two slidable rings 30 and 32 respectively bear against two fixed abutments 36 and 38 connected to the case 10.
  • the control device according to the invention is illustrated in the Figures in its application to the control of the engagement of a gear ratio of a gearbox having five forward gear ratios and one reverse gear ratio.
  • Conventional movable elements (not shown) for the alternative engagement of gears corresponding to the various gear ratios may be shifted by means of four slidable yokes respectively integral with parallel slides which are arranged in the case 10.
  • the two central yokes 40 and 42 are allocated to the engagement of the first four forward gear ratios. For this purpose, they are each slidable in a first direction parallel. to their common direction for changing to the corresponding ratio of even rank. Each of these two yokes is also slidable in the opposite direction for changing to a forward gear ratio of odd rank. Consequently, as shown in FIGS. 3a and 3b, the left central yoke 40 permits engaging the first and second forward gear ratios while the right central yoke 42 permits engaging the third and fourth forward gear ratios.
  • the control device further comprises two lateral end yokes 46 and 48.
  • the first lateral end yoke 46 which is on the left side as viewed in the Figures, permits changing to the reverse gear.
  • the reverse gear ratio is engaged by sliding said first lateral end yoke in the first direction, i.e. downwardly as viewed in FIG. 3b, corresponding to the direction for changing to the second and fourth forward gear ratios.
  • the control device comprises a first transverse abutment 50 disposed in the case 10 in confronting relation to the reverse gear changing yoke 46 and which prevents the sliding of the latter in the opposite direction, i.e. in the direction corresponding to changing to the first and third forward gear ratios.
  • the other lateral end yoke 48 permits the selection of and engaging the forward gear ratio of the highest rank.
  • Changing to the forward gear ratio of the highest rank, in the presently described embodiment the fifth gear ratio is effected by causing the lateral end yoke 48 to slide in the direction opposed to said first direction corresponding to the engagement of the reverse gear or the second and fourth forward gear ratios.
  • the control device includes a second transverse abutment 52 disposed in confronting relation to the lateral end yoke 48 and preventing the sliding of the latter in the first direction.
  • the selection and the engagement of the reverse gear are effected by an auxiliary control finger member 54 while the selection and engagement of the forward gear ratio of the highest rank are effected by the main control finger member as for the engagement of the forward gear ratios of lower rank.
  • the auxiliary control finger member 54 is pivotable about the axis of the main control shaft 12.
  • the auxiliary control finger member 54 is mounted on the control sleeve 18 and therefore on the main control shaft 12 to which it is connected in rotation and translation. Consequently, any rotation or movement in translation of the control shaft 12 causes the lateral translation of the simultaneous rotation of the two control finger members 20 and 54 which are interconnected.
  • the mean lateral distance D1 between the two control finger members 20 and 54 must, according to the present invention, exceed the mean lateral distance D2 between the two lateral end yokes 46 and 48. This feature ensures that the two control finger members can in no case be simultaneously in a position for engaging the reverse gear ratio and respectively the forward gear ratio of the highest rank.
  • the lateral end yoke 48 is provided with a ramp 56.
  • the end 44 of the main control finger member 20 cooperates with the ramp 56 when it is shifted in the first direction, i.e. in a direction corresponding to the engagement of the reverse gear, in order to cause the lateral disengagement of the end 44 of the main finger member 20 from the lateral end yoke 48.
  • the inclined ramp 56 is oriented to the right so as to cause the lateral disengagement of the main control finger member 20 and the lateral translation toward the right of the control shaft 12, i.e. to the side opposed to the other selection and changing yokes.
  • the lateral end yoke 48 has an extension 58 which constitutes a lateral abutment with which cooperates the end 44 of the main control finger member 20 when it is engaged in this lateral end yoke 48, for limiting its engagement travel toward the right and putting it in a position for selecting the forward gear ratio of the highest rank.
  • the lateral end yoke of the reverse gear 46 also includes an extension 60 which extends laterally toward the left, i.e. to the side opposed to the other selection yokes, and in confronting relation to which is located the free end 62 of the auxiliary control finger 54 when the main control finger member 20 is engaged in the other lateral end yoke 48, as can be seen in FIGS. 4a and 4b.
  • the lateral extension 60 permits effecting simultaneously the start of the engagement of the reverse gear ratio while the end 44 of the main control finger member 20 is progressively disengaged toward the right under the action of the ramp 56.
  • the selection of the forward gear ratio of the highest rank is effected by shifting the main control finger member 20 to the right until its free end 44 comes to occupy the position shown in FIGS. 4a and 4b in which it bears laterally toward the right against the lateral end abutment 58.
  • the free end 62 of the auxiliary finger member or the control finger member 54 is not engaged in the lateral end yoke 46 of the reverse gear proper, it is simply in confronting relation to the lateral extension 60.
  • the forward gear ratio of the highest rank is engaged (see FIGS. 5a and 5b) by causing a rotation of the control shaft in such manner as to cause the sliding of the lateral end yoke 48 in the upward direction as viewed in FIG. 4b.
  • the free end 62 of the auxiliary control finger member 54 is free to move upwardly in a direction parallel to the yoke 46 for engaging the reverse gear with which it does not interfere.
  • the engagement of the reverse gear is effected by causing a rotation of the control shaft 12 in such manner as to downwardly shift the free ends 44 and 62 of the control finger members 20 and 54.
  • the end 44 of the control finger member 20 comes to cooperate with the ramp 56 and cause its progressive lateral disengagement, while the free end of the control finger member 54 simultaneously causes the downward sliding of the lateral end yoke 46 of the reverse gear and therefore the engagement of the reverse gear ratio.
  • the two control finger members occupy the position shown in FIGS. 6a and 6b.
  • FIGS. 7a and 7b The second embodiment of the invention shown in FIGS. 7a and 7b will now be described. Elements which are similar or identical to those of the first embodiment are designated by the same reference numerals.
  • the control device here comprises a control stirrup 64 which is mounted on the control shaft 12 in such manner as to be freely pivotable and slidable relative to the latter.
  • the stirrup 64 is immobilized in translation relative to the case 10 of the gearbox by a fixed lateral positioning stud 66 which engages a transverse slot 68 provided in the upper branch 70 of the stirrup 64.
  • the left lateral branch, as viewed in FIGS. 7a and 7b, of the stirrup 64 constitutes the auxiliary control finger member whose free end 62 is permanently engaged in the lateral end yoke 46 for engaging the reverse gear.
  • the other right lateral branch 72 of the stirrup 64 extends in a direction parallel to the lateral branch 54 and has a driving yoke 74 at its end.
  • the driving yoke 74 is in juxtaposed relation to the lateral end yoke 48 for engaging the forward gear ratio of the highest rank, on the right side of the yoke 48 as viewed in FIGS. 7a and 7b.
  • the driving yoke 74 includes a central opening 76 in which is capable of extending and engaging the end portion 44 of the main control finger member 20 after it has been laterally disengaged from the yoke 48 under the action of the ramp 56.
  • the lateral end abutment 58 is provided on the driving yoke 76.
  • the five forward gear ratios are selected and engaged in a manner identical to that described with reference to the first embodiment of the invention, the control shaft 12 and the main control finger member being shifted independently of the auxiliary control finger member 54.
  • the reverse gear ratio is engaged by shifting downwardly (as viewed in FIG. 7) the free end 44 of the main control finger member 20 when the latter is engaged in the lateral end yoke 48.
  • This downward movement causes, by cooperation with the ramp 56, the lateral disengagement to the right of the free end 44 of the main control finger member 20 until the latter comes to be engaged in the opening 76 of the driving yoke 74.
  • pursuing this downward movement of the finger member 44 causes a simultaneous movement in the same direction of the free end 62 of the auxiliary control finger member 54 and therefore finally the engagement of the reverse gear ratio.
